  • Patent number: 11184950
    Abstract: A system and method for incorporating co-site interference impact in dynamic spectrum access for heterogeneous hierarchical networks where preprocessing is used to create lookup tables for the different types of co-site interference. The lookup tables reflect the weight of the spectral leakage lobes for all signals internal and external to the system under different conditions. Lookup tables can be used at any hierarchical entity that offer dynamic spectrum access services in a cloud services construct. Co-site interference impact becomes its own set of dynamic spectrum access services that can be added to a dynamic spectrum access capable system without impacting the other dynamic spectrum access computations needs such as computation that produce spatial separation. Co-site interference becomes a second order spatial separation that is abstracted in lookup tables and adaptable based on measured metrics such that different lookup tables can be used under different conditions.

  • Patent number: 10756789
    Abstract: A communication device includes a processing circuit, the processing circuit being configured as: mapping a first information bit part used for a receiving end to a corresponding channel based on a pre-set mapping rule so as to execute spatial modulation with respect to the first information bit part of the receiving end; allocating a transmission power to the receiving end; and controlling the transmission power allocated through a mapped channel to transmit a second information bit part used for the receiving end. In the case of the first information bit parts used for multiple receiving ends being the same, the channels mapped for multiple receiving ends are the same. The multi-user spatial modulation performs spatial modulation for multiple receiving ends at the same time through a multiplexing channel of the transmitting end, improving the additional modulation order and the data transmission rate which can be obtained by each receiving end.

  • Patent number: 10693544
    Abstract: Multiple antennas of a beamformer may simultaneously transmit wireless signals at different frequencies. The signals may comprise synchronized, identical wireless commands, each at a different carrier frequency. The transmitted signals may constructively and destructively interfere with each other at a receiver antenna, to form a beat signal. When the transmitted signals constructively interfere, the beat signal may cause a voltage in the receiver to exceed a threshold voltage. The threshold voltage may be a minimum voltage at which a device, which is operatively connected to the receiver antenna, is able to perform energy harvesting or wireless communication. The beamformer may operate under blind channel conditions, because the transmitted frequencies may be selected in such a way as to maximize peak power delivered under all possible channel conditions. The beamformer may deliver wireless power to a sensor or actuator that is located deep inside bodily tissue.

  • Patent number: 10693776
    Abstract: Some embodiments provide a method that generates different network measurements data (e.g., network topology, bandwidth estimation of different paths, etc.) for a pair of endpoints upon receiving a network administrative request (e.g., an application programming interface (API) request) or by other means (e.g., automatically and without intervention of a user). In some embodiments, the method is implemented by a network measurement agent operating on each endpoint and a centralized service component (e.g., web service layer) executing on a network manager machine (e.g., a controller) that responds to measurement requests. The network measurement agent probes the network periodically (i.e., in certain time intervals) or upon an API request that it receives through the network manager machine to gather the measurement data of a particular network topology between a pair of endpoints.

  • Patent number: 10680689
    Abstract: Embodiments of this disclosure provide techniques for determining a device's beam correspondence status. As used herein, a device is considered to have “beam correspondence” when the device's TX and RX antennas satisfy a calibration criteria. In one example, a device's TX and RX antennas satisfy the calibration criteria when a difference between quality parameters corresponding to reference signals transmitted and received using corresponding TX and RX beams is less than a threshold. In another example, a device's TX and RX antennas satisfy the calibration criteria when a list of indices ranking the device's TX beams matches a list of indices ranking the device's RX beams. The lists of indices may be derived by transmitting and receiving references signals according to the devices RX and TX beams, and then generating list of indices based on quality parameters of the respective RX and TX beams.

  • Patent number: 10673500
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) having partially coherent antennas may be configured for simultaneous transmissions on groups of antennas (e.g., multiple pairs of antennas). To achieve the benefits of simultaneous transmissions using groups of antenna that are partially coherent, without having the transmissions affect each other (e.g., interference), the UE may apply a hybrid closed-loop multiple-input multiple-output (MIMO) scheme among each antenna in the antenna groups where phase coherence can be maintained. Following the hybrid closed-loop MIMO scheme, the UE may apply a transparent diversity scheme across each antenna of the groups. Alternatively, the UE may first apply the transparent diversity scheme and next apply the hybrid closed-loop MIMO scheme.

  • Patent number: 10660101
    Abstract: Various embodiments disclosed herein provide for optimizing identification of a beam in a massive multiple-input multiple output (MIMO) system. The receiver device can select a beam to use for a transmission, and generate channel state information based on a selection of either a single stage beam selection process or a two stage beam selection process. According to an embodiment of the disclosure, the receiver can select which beam selection process to use based on the context of the receiver device. The receiver can select which beam selection process to use based on the long term signal to noise ratio, or the correlation metrics associated with the receiver and transmitter, or based on the path loss between the transmitter and receiver, or based on the location of the receiver relative to the transmitter.

    Abstract: A packet data transmission system comprises primary stations (PS) having signal transmitting and receiving means and antennas (PA1 to PA4) for propagating downlink signals and receiving uplink signals and a plurality of secondary stations (SS) able to roam within the coverage areas of the primary stations. Each secondary station (SS1) has signal transmitting and receiving means, a predetermined number of antennas (SA1 to SA4), and means for monitoring its radio environment. Information about the radio environment is relayed as an uplink signal to the respective primary station which modifies its mode of transmission of packet data signals. The secondary station in response to the modified mode of transmission of the downlink signals adapts its receiver resources to process the packet data signals and effect cancellation of any interference.

  • Patent number: 10594445
    Abstract: A method and system to improve the link budget of a wireless system using fast Hybrid Automatic Repeat Request (HARQ) protocol. In one embodiment of the invention, the Medium Access Control (MAC) logic in a base station determines whether the quality of the communication link with a mobile station is bad. When the MAC logic in the base station determines that the quality is bad, the base station uses a fast Hybrid Automatic Repeat Request (HARQ) protocol to indicate to the mobile station to send identical information to the base station in each of a plurality of successive or consecutive communication intervals before processing any received identical information from the mobile station. The fast HARQ protocol reduces the latency of receiving the identical information correctly, as compared with the current HARQ protocol.
